This is one of those questions — like the Maximalist or Minimalist debate — where my answer changes with each image that I see. What is your preference, dark, saturated walls that help make a bedroom a cocoon-like sleep sanctuary, or light, bright walls that pull in the morning sun?

As with so many other decorating decisions, this one might really depend on what sort of natural light your bedroom gets. While everything always looks better drenched in sunlight, a room that gets little light may be better served by a medium- to high-saturation deep color than by white walls.

But it also comes down to basic preference, which may have to do with personal differences about how we sleep best.
